The instrument essentially embodies the application of the principle of an injector for removing fluids or solids after they have been broken up and reduced tosemi-fiuid form, from body organs or cavities by draining or forcing them out through a drainage tube, which for example, may be an uterine catheter, the cannula of a trocar, or stomach tubefor the like, the device being also useful in the applicationfof medicants or anti-ferments to the walls of the cavities or organs, or for the internal inj ection of purgativesor the like.

Conditions are frequently encountered, particularly in cattle, where feed of one'kind or another will ball up into a compact, relatively solid mass within the stomach, resulting in a stoppage or interference with diges tion, and a consequent gas formation and swelling, ultimately resulting in death if the condition cannot be relieved. Similar conditions arise in other body organs or cavities which necessitate puncturing and'draining, as well as the application of medicines, purgatives and anti-ferments, etc. I 1

It has heretofore been customary to tap the cavity or organ with a suitable instrument, reference here being made to a trocar merely for convenience of description, it being understood however that the description applies equally well to its use with a stomach tube, uterine catheter, or to the cleaning and washing of any body organ or cavity. After the trocar has been inserted and the stylus withdrawmfiuids in the cavity or organ will immediately flow out through the drainage tube or cannula, andif solids are found by feeling with an impaction tube, it is now the custom to break them up as well as possible with the impaction tube,. usuallysome of them coming out of the drainagev tube or cannula and the balance being broken up so that it can be digested.

As far as I am aware no one has ever devised an instrumentwhich will insure the immediate removal of the entiremass from the organ or cavity and the ,completeflush- 2, 1931. Serial No. 572,512.

ing of the inside wall so that all harmful the pressure will tend to force compacted material toward the mouth of the drainage tube or cannula and will not force such foreign material more tightly into the convolutions; of the stomach, forexample, or increase the pressure in the stomach to the pain of the animal;

With the general objects named in view, the invention consistsin certain novel and useful features of construction and organization. of parts'as hereinafter described and claimed; and in order that it maybe fully understood, reference is made to the accompanying drawing, in which c Figure 1 is a foreshortened section taken through a trocar to illustratethe relationship between the stylus and drainage tube or cannula.

Figure 2 is a reduced 'foreshortened section 1 taken through a cannula with one form of the combined impaction and jet tube in .op-

the jet tube v Y In the drawing, wherelike reference char- I acters identify correspondingparts in all of the figures, 1 represents a stylus terminating at its front end in a piercing point 2 and at its;rear end in an operating handle 3, the c cavity to be drained or otherwise treated, the

stylus is then withdrawn, and if there is'liquid or gas under pressure in the pierced organ, it will frequently partially flow out the drainage or discharge tube as the stylus is withdrawn from position.

The preferred form of the combined jet and impaction tube for the: lavage or washing or treatment of the organ, is shown in Figures 2,4 and 5, said instrument comprising a tubular body portion 7 terminating at its front end in a return bend 8 formed with a jet orifice, the preferred proportion of the parts being such that the jet orifice 8a, when the body of the tube 7 is against the wall of the cannula, will lie in substantial alinement with the longitudinal axis of the cannula, the rear end of the jet tube being equipped with any suitable means 9 for detachable connection with a source of liquid'under pressure, such as a city water supply or with a gravity or pressure feed for a medicant, anti ferment,

or the like, depending upon thenature of the treatment to be appliec.

In order to center the jet tube in substantial ali-nement with the bore of the cannula so that the operator may manipulate the tube to attain the best jetting action, and at the same time to avoid as much as possible the clogging or stoppage of the liquid passing out through the cannula, the jet tube is rigidly secured to a guide ring 10 of such diameter as to be slidiugly received within the cannula so that the jet tube may be reciprocate-d to I break up a mass within the animal body and to secure the most efiicient washing of the material out through the cannula or dischargetube. In order to prevent the accidental projection of the guide ring 10 beyond the front end of the cannula where it might become caught and make it diificult to withdraw without injury to the animal, a stop 11 is secured adjacent the rear end of the tube 7,- the stop andguide ring 10 being so positioned that the former will engage the flange 6 of the cannula and prevent the forward movement of the jet tube and ring beyond the dotted line position shown in Figure 2.

With this type of construction it Will be evident that the jet orifice 8a will always wash material toward the cannula, and that the return bend construction also offers protection to the jet orifice to prevent clogging or stoppage.

In the construction shown in Figures 3, 6 and 7, a modified type of jet tube is illustrated, which is particularly useful in breaking up balls of fibrous material, such as hay or hair, said jet tube comprising a body portion 12 having a closed front end 13. The body 12 rearward of its front end is tubular and is provided at its rear end (not shown) with a detachable connection. for attaching a source of liquid supply. The front end of the jet tube 12 is provided with a series of 'rearwar'dly faci'ng'hooks 14 which may be used to catch into a ball of fibrous material for the, purpose of tearing it up so that it may be pulled out through the cannula, and to assist in forcing the material toward the mouth of the cannula, and to flush the cavity or organ,-a source of liquid supply is connected to the tube 1-2, the liquid jetting out through the jet orifices 15 formed in certain of the'foremost hooks 14, it being evident that the hooks, in effect, form protective housingsor hoods for the jets to prevent the clogging thereof when in use, and that the action of the rearwardly etting liquid is substantially similar as far as flushing is concerned to the construction shown in Figure 2. Vith this type of construction,-

the devicehas some play within the cannula so that its front end can be projected sidewise out of axial alinement with the bore of the cannula, although, it will be obvious that, if desired, the'hooks 1 may be made sufficiently wide or long to come into guiding contact with the wall of the cannula and thus maintain the-device in substantial alinement therewith.

From the above description it will be evi:

dent that I have described and claimed a construction embodying all of the features of advantage set forth as desirable, and it is to be understood that I reserve the right to make all changes falling within the spirit of the invention and without the ambit of the prior art. 7 r

. I claim:

1. A device of the character described comprising a drainage tube, a liquid supply tube extending through the drainage tube, and a guide bearing a fixed relation to the supply tube and a sliding relation to the drainage tube. V

2.- A device of the character described comprising a drainage tube, a liquid supply tube extending through the drainage tube, a guide bearing a fixed relation to the supply tube and a sliding relation to the drainage tube, and a stop to prevent projection of the sup ply tube and guide beyond the front end of the drainage tube.

3. A device of the character described comprising a drainage tube, a liquid supply tube extending through the drainage tube, and rearwardly facing hooks adjacent the front end of said tube, certain of said hooks being formed with rearwardlyfacing jet openings.

14. An impaction tubehaving its front end formed in a return bend terminating in a jet orifice.

5. An impaction tube having its front end provided with a jet orifice, and a-tubular guide carried by said tube and adapted for sliding engagement with the bore of a cannu a.

6. An impaction tube having its front end provided with a jet orifice, and a guide member secured to said tube and being ada ted for sliding engagement with the internal ore of a cannula.

7. A device of the character described comprising a drainage tube, a liquid supply tube extending through the drainage tube and having one end formed in a return bend terf minating in a jet orifice, and a guide member for positioning the supply tube within the drainage tube and to maintain the jet orifice in substantial alinement with the bore of the drainage tube.

In testimony whereof I afiix my signature.
